What is a better way to prep for your AP exam?

As it is getting closer and closer to the month of May, I am beginning to review/prep for my AP exams. I have review books for all my subjects, but I was wondering what is the best way to go through them. Is it best to alternate subjects day by day? For example, study for microeconomics one day, government the next, and stats on the third. Or is it best to go through a whole review book for a subject before moving on to the next?

The subjects I am taking AP stats, micro, macro, and government. Also, I am also the type of student that would study the night before for a final, and has for the most part been successful. Therefore the latter plan that I mentioned is more appealing but I wanted to hear from the CC community.
